The rhizomes are long and branched and have internodes of 2cm. The pseudobulbs are spaced 6.5cm apart along the rhizome and grow at an acute angle and appear appressed against it. The pseudobulbs are shaped terete and measure 4cm long, the pseudobulbs are as wide as the rhizome. The leaves are petiolate, the petiole measures 1cm long. The leaf blades are shaped elliptic-oblong to lanceolate and have narrowly obtuse to apiculate apices. The leaf blades measure 6.7-11cm long and 2.35-3cm wide.

The Inflorescence

The inflorescence is synanthous. The peduncle measures 5.5-7cm long. The rachis is nodding and measures 9cm long. The flowers are spaced 1.6mm apart.

The Flowers

The flower colour is light brown, the flowers open widely. The sepals are shaped ovate-oblong and have shortly acute apices. The sepals measure 4mm long and 1.6mm wide. The petals are shaped elliptic-oblong and have acute apices. The upper margins of the petals are irregular and concave. The petals measure 3.3mm long and 1.6mm wide. The labellum is held parallel to the column and does not have distinct side lobes. The apical section is shaped broadly triangular and has a short acuminate apex. The labellum measures 2mm long and 3mm wide. The labellum is wider at its apex; the basal margin is minutely erose. The labellum has two small keels at its base which are transversely connected. The column is small and curved. The column measures 1.4mm long. The apical hood is a trapezoid shape and has a truncate apex. The margin of the apical hood is denticulate. The stelidia grow from just above the middle of the column and are equal to the apical hood. The stelidia are shaped obliquely oblong and have obtuse apices.
